With Explosion Or Breaking Container To Implode Patents (Class 166/299)
  • Patent number: 11473383
    Abstract: A method of selectively expanding a wall of a tubular includes assembling an expansion tool comprising a plurality of bi-directional boosters, arranging a predetermined number of explosive pellets a serially-arranged column between the bi-directional boosters, positioning a duel end firing explosive column tool within the tubular, and detonating the bi-directional boosters to simultaneously ignite opposing ends of the serially-arranged column to form two shock waves. The shock waves collide to create an amplified shock wave that travels radially outward to impact the tubular and expand a portion of the tubular wall radially outward, without perforating or cutting through the portion of the wall, to form a protrusion of the tubular at the portion of the wall. The protrusion extends into an annulus adjacent an outer surface of the wall of the tubular.

  • Patent number: 11441407
    Abstract: A well tool includes a perforating gun including multiple shaped charges, a sheath encapsulating the perforating gun and powdered acid in an internal chamber defined by the sheath. The perforating gun is lowered to a depth into a wellbore formed in a subterranean zone. The multiple shaped charges are fired to form multiple perforations in the wellbore at the depth. The multiple perforations provide access to the subterranean zone at the depth. The sheath, which covers at least some of the multiple shaped charges, breaks responsive to at least some of the multiple shaped charges being fired. The powdered acid in the internal chamber is applied to the subterranean zone responsive to the multiple shaped charges being fired. The powdered acid reacts with and weakens the subterranean zone at the depth to ease flow of hydraulic fracturing fluid into the subterranean zone at the depth.

  • Patent number: 10494886
    Abstract: A valve device selectively communicates annulus pressure or pressure from a hydraulic circuit to an actuation piston of a borehole tool to directly or indirectly set the borehole tool. A valve member is held against spring bias by a retainer whose physical properties can be remotely changed to release the force of the bias to move the valve member which in turn moves an actuating piston to set the borehole tool. The compressive strength of the material can be impacted by electric current that directly or indirectly such as with the generation of heat results in weakening the retainer. The retainer material may be surrounded with a sleeve to enhance compressive strength until the remote signal is applied such as with wireline or electric line. Other property changes to the retainer are contemplated such as volume change, shape change, change in state or change in tensile or compressive strength.

  • Patent number: 9394767
    Abstract: A method and apparatus is described for modifying downhole wellbore pressure at the instant that an explosive event occurs. By a significant temporary reduction in wellbore pressure, for example, an explosive cutter will be able to cut through thicker pipe in a deep well with high hydrostatic pressure. A favorable transient wellbore pressure is achieved by the selective timing of implosion and explosion devices, to improve the performance of certain explosive tools when subsequently initiated, such as shaped charge explosive cutters, severing tools, setting tools and perforating guns. As part of the system, each implosion or explosion device is initiated by a detonator having a preprogrammed control unit with a preselected timing delay to take advantage of the temporarily lowered wellbore pressure.

A packer swelling verification system can include a swellable material which swells in a well, and a well tool which is conveyed to the packer in the well. The well tool receives an indication of a degree of swelling of the swellable material. A method of verifying whether a swellable material has swollen in a well can include positioning a conductor proximate the swellable material, whereby the conductor parts in response to swelling of the swellable material, and detecting whether the conductor has parted.

  • Patent number: 9057261
    Abstract: Methods and systems are provided for fracturing rock in a formation to enhance the production of fluids from the formation. In one exemplary method, one or more wells are drilled into a reservoir, wherein each well comprises a main wellbore with two or more lateral wellbores drilled out from the main wellbore. One or more explosive charges are placed within each of the two or more lateral wellbores, and the explosive charges are detonated to generate pressure pulses which at least partially fracture a rock between the two or more lateral wellbores. The detonations are timed such that one or more pressure pulses emanating from different lateral wellbores interact.

  • Patent number: 8939210
    Abstract: A pipe severing tool is arranged to align a plurality of high explosive pellets along a unitizing central tube that is selectively separable from a tubular external housing. The pellets are loaded serially in a column in full view along the entire column as a final charging task. Detonation boosters are pre-positioned and connected to detonation cord for simultaneous detonation at opposite ends of the explosive column. Devoid of high explosive pellets during transport, the assembly may be transported with all boosters and detonation cord connected.

  • Patent number: 8851191
    Abstract: A method for unseating a threaded connection of wellbore tubing within the wellbore. The method utilizes a back-off tool which consists of a tubular metal housing, a shaped charge and HNS detonating cord within the housing, and an explosive material attached to the housing. The back-off tool is detonated near the threaded connection, creating a shockwave that strikes the threaded connection with sufficient force to unseat the connection.

  • Patent number: 8794326
    Abstract: A method of adjusting a pressure reduction to occur in a wellbore following firing of at least one perforating gun can include determining a desired free gun volume which corresponds to a desired pressure reduction in the wellbore resulting from firing of the perforating gun, and varying a free gun volume of the perforating gun until the free gun volume is substantially the same as the desired free gun volume. A well system can include at least one perforating gun positioned in a wellbore, the perforating gun comprising multiple perforating charges and a free gun volume, and the free gun volume being reduced by presence of a flowable material about the multiple perforating charges.

  • Patent number: 8757263
    Abstract: This invention relates to the oil and gas industry and to exploration and production of water resources, in particularly, for stimulation of fluid flow to the well, e.g., for higher oil production, productivity index, and recovery factor. The disclosed device and method can be used for higher permeability of the pay zone due to creation of a network of microcracks in the bottomhole formation zone and facilitates to increase the flow of oil, or other fluids, from the reservoir to the well. Generation of cyclic pressure pulses with varied amplitude and time parameters and proper localization of pulses in space through mechanism of convective combustion provides a “soft” impact upon the wellbore without risk of damage or formation consolidation; the said impact is achieved by using a device which is a downhole cyclic pressure generator operating by a consecutive combustion of layers of compositions having different combustion rates.
